Tom Arnold's dream of becoming a dad has finally come true! After years of fertility issues, the "True Lies" actor, 54, welcomed his first child, a son named Jax Copeland Arnold, on April 6, his rep confirms to Us Weekly.

Arnold first broke the news that his wife was expecting earlier this year during a guest co-hosting stint on "The View" in January. "I'm pregnant," he joked. "I have put on, like, 40 pounds. My wife is pregnant too. We're having a baby."

The dad-to-be was ecstatic -- and with good reason. Arnold, who was married three times before tying the knot with Groussman in 2009, has struggled with infertility for years. In order to conceive Jax, he and his wife had to endure several rounds of in vitro fertilization. But it all paid off.
